It's still unclear why Matthew Vanhofwegen was shot multiple times last month by a single police rifle. The Bureau of Criminal Apprehension, a division of the MN Department of
Public Safety, says an investigation is "active and ongoing."

Court documents suggest that Vanhofwegen kept several guns around his New Brighton home. But a drug task force didn't know that for certain until after the raid.

In mid-August, an anonymous informant known in court documents as
"Concerned Citizen" told a New Brighton police officer and investigator with the Ramsey County Violent Crime Enforcement Team that Vanhofwegen kept
marijuana plants on the second-floor deck. Another unnamed
source spoke generally of the home as a "problem" in the neighborhood.

The investigator checked with other New Brighton police officers, who said they'd "recently observed an increase in late night vehicle traffic"
at the home. It's located in the 1500 block of 20th Avenue
Northwest.

Investigators went to inspect for themselves. One of them would later write:

It
appeared [from neighboring property] that a black draping had been put
up around the deck's railings to conceal the plants, however, some of it
had fallen down exposing the suspected marijuana plants.

The
investigators also looked at Vanhofwegen's conviction record in Ramsey
County, which consists of non-violent crimes -- possession of drug paraphernalia (1988), drug offense
misdemeanor (1989). Judge Joy D. Bartscher signed the warrant.

According to the Bureau of
Criminal Apprehension, Vanhofwegen spotted officers from across Ramsey County approaching his
home, around 2 p.m.
Aug. 27, and went inside. The officers knocked and announced they had a warrant, but he didn't respond. The forced the door open.

In the hallway of his home, Vanhofwegen allegedly grabbed the barrel of Maplewood
Police Officer Joseph Steiner's rifle. "A
struggle ensued and Officer Steiner shot Vanhofwegen," according to a statement released the next day.

Steiner was placed on a standard
administrative leave. He has not returned messages seeking comment.

Vanhofwegen was taken to the Hennepin County Medical Center. Court documents show that police walked away with Vanhofwegen's

Randy Gustafson, a spokesman for the Ramsey County Sheriff's Office, had no comment on the case. He also did not have an update on Vanhofwegen's condition.

No charges have been filed against Vanhofwegen.
